What Is An LCR Meter? Uni-T UT622A First Look

It dawned on me that some people don't know the difference between a multimeter and a LCR meter, so I figured it would be a great first look at the UT622A to explain what a LCR meter is and to take the UT622A out for a spin!

My first time seeing a LCR meter in action, and I am pretty impressed.

[@qzorn4440]

Most excellent LCR video and they do have their place in troubleshooting. 😎 Thanks.

[@jb3757]

good job, I'm waiting for the review, as I'm taking this meter for an LCR candidate.

[@amrelsharkawy6701]

Excellent Review .. Thanks a lot

[@AnotherMaker]

Very cool tests. I'm sure that review took a while to do. I'm kind of curious if that micro usb outputs anything and does more than just charging. I feel like it might.

[@TheDefpom]

Capacitive Reactance, and Inductive Reactance are the terms for AC measurements for capacitors and inductors.

[@SimpleElectronics]

I got that far before my brain said "yeah, not tonight man"

[@biomed24]

Hello, inquiry: What voltage applies for ESR test on capacitors?

[@TheDefpom]

Did you null the meter out before doing the measurements ? the lead resistance at the end there was a bit high, wold have given even better resistance readings otherwise.

[@SimpleElectronics]

I did not, the manual for this thing is huge lol

[@pileofstuff]

Good reminder. When I zeroed mine it made a noticeable difference (I assume mostly based on the stray reactance in the leads)

[@juancarlossandoval5628]

Can this be used to measure battery like 18650 internal resistance?

[@biomed24]

can the UNIT ut 622e be used for on board testing?

[@moshet842]

I almost got this UNI-T but ended up getting the DE-5000 instead after seeing a comparison someone did on youtube.

[@user-ty2uz4gb7v]

Are those buttons as irritating as I've heard?

[@kugelschreiberzusammenbaue3585]

what are the readings of the small ceramic cap with a multimeter ?

[@amaraamara-jq2xi]

Thank you very much

[@TRONMAGNUM2099]

I'd like to see an accuracy comparison between the really cheap LCR meters and yours. I bought a super cheap one off banggood for about 10 bucks and then a slightly nicer one for about 30 bucks. I'd like to see if the accuracy is much poorer on the cheap ones.

[@SimpleElectronics]

I'll see what I can do, thanks for the suggestion!

[@clems6989]

There are some comparisons on youtube. Youll be surprised at how good even the cheap ones do..

[@humanresource9659]

It takes multiple measurements, it's a multimeter... Could you do a side by side comparison of the UT 622a versus the Sanwa LCR 700?

[@SimpleElectronics]

I would love to, if I can get someone to send it to me, I'll do it.

[@electroniquepassion]

Hello, j’aime bien cette marque 👍

[@SimpleElectronics]

Moi aussi! J'aime bien Uni-T, ils font des bons outils!

[@sumitm8904]

Can I measure the LCR of NFC tag?

[@SimpleElectronics]

I can't see why not?

[@Jnglfvr]

At 14:33 don't you have that electrolytic capacitor wired backwards?

[@SimpleElectronics]

It uses AC to test, so polarization doesn't matter

[@Jnglfvr]

@@SimpleElectronics Interesting. So why does polarity matter in DC but not AC?

[@ooltimu]

What's the maximum capacitance it can measure?

[@arsenicjones9125]

Stats for the UNI-T 622A 99.999mF @ 100/120Hz, 9.9999mF @1kHz and 999.99uF @ 10kHz. If you get a C or E model it can do 99.999uF @ 100kHz also. 0pf is the minimum for all frequencies w variable amounts of trailing zeros.

[@ooltimu]

@@arsenicjones9125 I've seen the specs, but I was curious if someone really pushed it to the limit to see if those are real and accurate

[@nicepeoplehd1319]

thank you sir but the real question is that we can test the components on the pcb without removing

[@clems6989]

To me every LCR meter should do ESR as well.

[@yurkshirelad]

I bought my multimeter from Canadian Tire. 😁

[@Ove_Bjerknes]

08:55 - LOL. Better uggly and smart than cute and dum :)

[@user-ev5vs5xs9n]

❤

[@johnlucier8572]

It's not a multimeter
